Abstract

A shift operating device for a bicycle is provided to change gears of the bicycle. The shift operating device is coupled to the front or rear derailleur via a shift cable. The shift operating device is also coupled to a gear indicator device via an indicator cable. The shift operating device has an attachment portion, a hand operating portion, and a take up member. The attachment portion is adapted to be coupled to a portion of a handlebar of the bicycle. The hand operating portion is coupled to the attachment portion to move between a plurality of shifting positions. The take up member is operatively coupled to the hand operating portion to move in response to movement of the hand operating portion. The take up member has a peripheral winding surface, a first cable attachment point and a second cable attachment point. The first and second cable attachment points of the take up member are located such that shift and indicator cables extend outwardly from the take up member and winds about the peripheral winding surface.

Claims

exact text as granted — not AI-modified

What is claimed is:

1. A shift operating device comprising:
a bicycle attachment portion;
a hand operating lever pivotally coupled relative to said attachment portion about a rotational axis;
a take up member fixedly attached to said hand operating lever to move about said rotational axis in response to movement of said hand operating lever, said take up member having a peripheral winding surface, a first cable attachment point and a second cable attachment point,
said first and second cable attachment points of said take up member being located such that first and second cables extend outwardly from said take up member and wind about said peripheral winding surface; and
a first cable housing support located adjacent said take up member, and having a first cable housing receiving bore.

2. A shift operating device according to claim 1 , further comprising
a second cable housing support is located adjacent said take up member, and having a second cable housing receiving bore.

3. A shift operating device according to claim 2 , wherein
said second cable housing receiving bore is same diameter as said first cable housing receiving bore.

4. A shift operating device according to claim 2 , wherein
said second cable housing receiving bore has a smaller diameter than said first cable housing receiving bore.

5. A shift operating device according to claim 2 , wherein
said second cable housing support has a slit extending from said second cable housing receiving bore.

6. A shift operating device according to claim 2 , wherein
said first and second cable housing supports are located adjacent each other and extend longitudinally in the same direction.

7. A shift operating device according to claim 1 , wherein
said second cable is an indicator cable having a nipple formed at both ends and one of said nipples is coupled to said second cable attachment point.

8. A shin operating device according to claim 1 , wherein
said first cable is a shift cable with a first shift cable end coupled to said first cable attachment point.

9. A shift operating device according to claim 8 , wherein
said second cable is an indicator cable with a first indicator cable end coupled to said second cable attachment point.

10. A shift operating device comprising:
a bicycle attachment portion;
a hand operating lever pivotally coupled relative to said bicycle attachment portion about a rotational axis; and
a take up member attached to said hand operating lever to move about said rotational axis in response to movement of said hand operating lever, said take up member having a first cable attachment point and a second cable attachment point;
a first cable housing support located adjacent said take up member, and having a first cable housing receiving bore to guide said first cable from said take up member; and
a second cable housing support located adjacent said first cable housing support; and having a second cable housing receiving bore to guide a second cable from said take up member, said second cable housing receiving bore being arranged to extend longitudinally in the same direction as said first cable housing bore.

11. A shift operating device according to claim 10 , wherein
said take up member has a first peripheral surface for guiding the first cable.

12. A shift operating device according to claim 11 , wherein
said take up member has a second peripheral surface for guiding the second cable.

13. A shift operating device according to claim 10 , wherein
said second cable housing receiving bore is substantially same diameter as said first cable housing receiving bore.

14. A shift operating device according to claim 10 , wherein
said second cable housing receiving bore has a smaller diameter than said first cable housing receiving bore.

15. A shift operating device according to claim 10 , wherein
said second cable housing support has a slit extending from said second cable housing receiving bore.

16. A shift operating device according to claim 10 , wherein
said second cable is an indicator cable having a nipple formed at both ends and one of said nipples is coupled to said second cable attachment point.

17. A shift operating device comprising:
a bicycle attachment portion;
a hand operating portion movably coupled to said bicycle attachment portion;
a take up member operatively coupled to said hand operating portion to move in response to movement of said hand operating portion, said take up member having a shift cable attachment point and an indicator cable attachment point, said take up member having a peripheral winding surface;
an indicator cable having a first end and a second end with said first end located in said peripheral surface of said take up member; and
a gear indicator having an indicator housing with an indicator member coupled to said second end of said indicator cable for movement of said indicator member relative to said indicator housing.

18. A shift operating device according to claim 17 , wherein
said hand operating portion is a pivotally mounted lever.

19. A shift operating device according to claim 18 , wherein
said take up member has a first peripheral surface for guiding a shift cable.

20. A shift operating device according to claim 19 , wherein
said take up member has a second peripheral surface for guiding said indicator cable.

21. A shift operating device according to claim 18 , further comprising
a shifting cable housing support located adjacent said take up member, and having a shift cable housing receiving bore.

22. A shift operating device according to claim 21 , further comprising
an indicator cable housing support located adjacent said take up member, and having an indicator cable housing receiving bore.

23. A shift operating device according to claim 22 , wherein
said indicator cable housing receiving bore is substantially same diameter as said shift cable housing receiving bore.

24. A shift operating device according to claim 23 , wherein
said indicator cable housing receiving bore has a smaller diameter than said shift cable housing receiving bore.

25. A shift operating device according to claim 23 , wherein
said shift cable housing support and said indicator cable housing support are located adjacent each other and extend longitudinally in substantially the same direction.

26. A shift operating device according to claim 18 , wherein
said indicator cable has a nipple formed at both ends and one of said nipples is coupled to said second cable attachment point.
